BlRD-CAGE SCREEN.

SPECIFICATION forming part of Letters Patent No. 348,012, dated August 24, 1886.

Application filed May 17, 1886. Serial No. 202,364. (No model.)

To all whom, it may concern.-

Be it known that 1, ANDREW B. HENDRYX, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Bird-Cage Screens; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1, a perspective view of a rectangular screen in its most contracted form, broken lines indicating expanded screen; Fig. 2, a side view of the screen at the overlap and as in the contracted position, broken lines illustrating the expansion; Fig. 3, a vertical central section through the interlocking device.

This invention relates to an improvement in cage screens, such as are particularly adapted for bird-cages, to prevent the scattering of the seed. In the usual construction the size of the screen is fixed so that each screen can only be used with a certain size cage, and forthe same reason requires a great amount of space in transportation and storing, and also necessitates the dealers carrying a large assortment of sizes.

The object of thisinventiou is to avoid these difficulties; and it consists in the construction as hereinafter described, and more particularly recited in the claim.

The screen is formed from one or more pieces of metal, generally sheet-brass, perforated andverse side, as shown in Fig. 3, securely interlocking the parts, but so as to allow the overlapped parts to slide upon each other, and the screen to be expanded or contracted as desired.

In screens adapted for rectangular cages, as shown in Fig. 1, it is preferred to construct the screen in four parts, to permit an'even adjustment of all the sides.

In screens for circular cages the screen may be of one or more parts, according to the extent of adjustment desired. By this construction the screens may be nested for transportation and storage, arranging them at the various points .of adjustment from the greatest extent downward to the smallest, thus forming a solid package which is not liable to injury in packing, transportation, or otherwise.

I am aware that it-is not new, broadly considered, to make an adjustment in extent between two parts by sliding the one upon the other, and therefore do not broadly claim such method of expansion or contraction.

I claim- As an article of manufacture, the hereindescribed cage-screen made in several parts of perforated sheet metal, the said parts adapted to surround the cage and stand in a vertical plane, the adjacent ends of the said parts overlapping each other in said vertical plane, the one part at such overlapping points constructed with longitudinal slots, and the other constructed with corresponding tongues extending through said slots and so as to cmbrace the opposite side of said slotted part, substantially as described, and whereby the said parts are interlocked at their overlapping points and made adjustable for various sizes of cage.
